mysqlでRailsプロジェクトをスタート
プロジェクトディレクトリを作成し,bundle init ,さらにbundle install
$ mkdir dk_port $ cd dk_port $ bundle init
bundle init
で作成されたGemfileでrailsを有効にする
$ emacs Gemfile
source "https://rubygems.org" gem 'rails'
bundleで入れるものは vender/bundle に配置する.railsコマンドについても,bundle exec ~~
として利用する.
gem をインストールするパスを指定して,bundle install
する.
$ bundle install --path vendor/bundle
rails new で プロジェクトを新規作成
ここで,プロジェクトを新規作成.データベースにはMySQLを指定する.
$ bundle exec rails new . -d mysql -T --skip-bundle --edge
bundle install すると必要なGemが入る
$ emacs Gemfile source 'https://rubygems.org' gem 'rails', github: 'rails/rails' gem 'arel', github: 'rails/arel' # Use mysql as the database for Active Record gem 'mysql2' # Use edge version of sprockets-rails gem 'sprockets-rails', github: 'rails/sprockets-rails' # Use SCSS for stylesheets gem 'sass-rails', github: 'rails/sass-rails' # Use Uglifier as compressor for JavaScript assets gem 'uglifier', '>= 1.3.0' # Use CoffeeScript for .js.coffee assets and views gem 'coffee-rails', github: 'rails/coffee-rails' # See https://github.com/sstephenson/execjs#readme for more supported runtimes # gem 'therubyracer', platforms: :ruby # Use jquery as the JavaScript library gem 'jquery-rails' # Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks gem 'turbolinks' # Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder gem 'jbuilder', '~> 1.2' group :doc do # bundle exec rake doc:rails generates the API under doc/api. gem 'sdoc', require: false end # Use ActiveModel has_secure_password # gem 'bcrypt-ruby', '~> 3.1.2' # Use unicorn as the app server # gem 'unicorn' # Use Capistrano for deployment # gem 'capistrano', group: :development # Use debugger # gem 'debugger', group: [:development, :test]
Gitリポジトリを初期化
この辺りでgitを設定する.
$ git init $ git add . $ git commit -m "first commit"
プロジェクト用のMySQLユーザーを作成する
MySQLにログインしてユーザーを作成する.
$ mysql -u root -p # パスワード入力
ユーザー作成.
mysql> GRANT ALL PRIVILEGES ON *.* TO ユーザー名@localhost IDENTIFIED BY 'パスワード';
ユーザーができているか確認
mysql> select host,user from mysql.user;
config/database.ymlで設定を編集
$ emacs config/database.yml # MySQL. Versions 4.1 and 5.0 are recommended. # # Install the MYSQL driver # gem install mysql2 # # Ensure the MySQL gem is defined in your Gemfile # gem 'mysql2' # # And be sure to use new-style password hashing: # http://dev.mysql.com/doc/refman/5.0/en/old-client.html development: adapter: mysql2 encoding: utf8 database: railsapp_development pool: 5 username: DBユーザー名 #ここと password: DBパスワード #ここだけ socket: /tmp/mysql.sock host: localhost charset: utf8 collation: utf8_general_ci # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: mysql2 encoding: utf8 database: railsapp_test pool: 5 username: DBユーザー名 password: DBパスワード socket: /tmp/mysql.sock host: localhost charset: utf8 collation: utf8_general_ci production: adapter: mysql2 encoding: utf8 database: railsapp_production pool: 5 username: DBユーザー名 password: DBパスワード socket: /tmp/mysql.sock host: localhost charset: utf8 collation: utf8_general_ci
rails g を用いてControllerを作成し,確認
$ bundle exec rails g controller Hello index $ bundle exec rails s
http://localhost:3000/hello/index
削除するには
$ bundle exec rails destroy controller Hello index
